Aggressive Cancers Feed Off the Brain’s Nerves

Cancer cells have the ability to connect to and feed off of neurons in the brain, according to three studies published in Nature on Wednesday (September 18). The findings may explain why certain brain cancers are so difficult to treat and could... Continue Reading →

Synapses of the reward system at stake in autistic disorders

Autism spectrum disorders are a heterogeneous group of neurodevelopmental disorders, one of the main characteristics of which is impaired social communication. But what happens in patients' brains that disrupts their social skills? According to scientists from the Universities of Geneva... Continue Reading →

Scientists discover fundamental rule of brain plasticity

Our brains are famously flexible, or “plastic,” because neurons can do new things by forging new or stronger connections with other neurons. But if some connections strengthen, neuroscientists have reasoned, neurons must compensate lest they become overwhelmed with input. In... Continue Reading →

Building a Brain, Cell by Cell: Researchers Make a Mini Neuron Network (of Two)

The human brain is an exquisitely complex, organic CPU, made of trillions of connections between many billions of neurons. Understanding such a complicated organ is a massive scientific undertaking, and researchers often use simplified models to uncover small pieces of... Continue Reading →

How The Brain Resets During Sleep

Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses – the junctions between nerve cells – grow strong and large during the stimulation of daytime, then shrink by... Continue Reading →
